Penalties for Not Maintaining an ISC Register in Ontario

Most Ontario corporations that fall behind on their individuals with significant control (ISC) register did not decide to ignore it — they simply never built it into their routine corporate housekeeping, alongside minute-book updates and annual filings. The problem is that this particular gap is not a purely administrative one. The Business Corporations Act (OBCA) treats a compliant ISC register as a legal requirement backed by its own offence provisions, not a best practice.

Understanding what is actually at stake — for the corporation and, in some circumstances, for the people running it — makes it much easier to justify fixing the gap now rather than waiting for it to surface at the worst possible moment.

Why the ISC Register Isn't Optional Paperwork

Every private OBCA corporation is required to identify, record, and keep current the individuals who ultimately own or control it. Unlike some corporate formalities that mostly matter for internal governance, this register exists to serve a public transparency purpose, and the OBCA backs that purpose with enforceable consequences for non-compliance — not merely a recommendation to "keep good records."

What Non-Compliance Actually Looks Like

Falling out of compliance rarely happens all at once. In practice, it tends to look like:

1. Never creating the register in the first place, treating it as something to deal with "later" after incorporation.
2. Letting it go stale after a share transfer, a new investor coming in, or a shareholders' agreement changing who acts jointly with whom.
3. Recording incomplete information — missing a required identifying detail for a significant control holder.
4. Providing false or misleading information, whether knowingly or through carelessness, when the register is prepared or updated.
5. Failing to produce the register when a regulator, government official, or other party legally entitled to request it does so.

Who Can Be Held Responsible

This is not automatically confined to "the corporation" as an abstract entity. Depending on the circumstances, the OBCA's offence provisions can extend responsibility to:

• The corporation itself, as the entity legally required to maintain the register.
• Directors and officers, particularly where they knowingly caused, authorized, or permitted the corporation's non-compliance, or where they knowingly provided false or misleading information for the register.
• Shareholders, in narrower circumstances, if they knowingly provide false or misleading information for inclusion in the register.

The involvement of individual directors and officers is exactly what makes this different from a purely corporate-level filing miss — it is one of a small number of compliance gaps that can follow the people running the business personally, not just the company.

What's at Stake

The OBCA's offence provisions for non-compliance can expose the corporation — and, in some cases, its directors, officers, or shareholders personally — to fines and other court-ordered consequences. In circumstances involving knowingly false or misleading information, the exposure can be more serious still. Because the exact financial amounts and specific penalty structure are technical and can change, confirm the current framework with your corporate lawyer rather than relying on a number you may have seen quoted elsewhere.

Beyond the formal legal exposure, a missing or stale ISC register is also a practical red flag that surfaces at exactly the wrong moment — during due diligence for a financing, a sale, or a loan application — when it signals to the other side that the corporation's records generally may not be in order.

How to Get and Stay Compliant

• [ ] Confirm whether your corporation currently has an ISC register at all, and if so, when it was last updated.
• [ ] Identify every individual who meets the significant-control threshold, including through joint arrangements and holding structures.
• [ ] Record the required identifying information completely and accurately for each individual.
• [ ] Build a trigger into your corporate housekeeping so that share transfers, new investors, and shareholders' agreement changes automatically prompt an ISC register review.
• [ ] Keep the register together with the rest of your minute book, where it will actually be checked during financing or sale due diligence.
• [ ] When in doubt about whether someone meets the threshold, get it reviewed rather than guessing.
